The attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or launch the file. Successful exploitation could allow the attacker to execute arbitrary code on the user\u2019s system.\r\n\r\nThe Cisco WebEx Players are applications that are used to play back WebEx meeting recordings that have been recorded by an online meeting attendee. The player can be automatically installed when the user accesses a recording file that is hosted on a WebEx server.\r\n\r\nCisco has updated the affected version of the Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players to address this vulnerability.\r\n\r\nThere are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180103-wnrp [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180103-wnrp\"]",
